The timing of the capacity to be bound. In different seasons and ages, one and the same thing can be bonded in various ways, and different things are not related to one and the same bond in the same way. Nor are wholes always recomposed in the same way. From this we can point out that someone who was easy going and showy as a young man becomes a more stable and prudent adult, while an old man is more suspicious and morose, and a very old man is full of blame and loathing.
The number of things that can be bound. Thinking persons turn away from sensible things and are bound by divine things. Pleasure seekers descend through vision to the abundances of touching. Moralists are attracted by the amusement of conversation. The first are heroes, the second are natural, and the third are rational. The first are higher, the second lower, the third in between. The first are said to be worthy of the heavens, the second of life, the third of feeling. The first ascend to God, the second cling to bodies, the third move away from one extreme and approach the other.
The degrees of things that can be bound. Children are less bound by their natural feelings, because their nature is absorbed in growth and is disturbed by great changes, and all their nutrition is given over to growth and the structuring of the individual. But they clearly begin to be open to being bound in the fourteenth year, for even though at that age they are still involved in growth, their rate of growth is not as fast and as great as when they were children. And in the stable period of adulthood, men have a greater strength in their semen and, as a result, seem to be more subject to being bound. Furthermore, adolescents and young men seem to be more sexually excited for the reason that they are on fire for a long time because of the novelty of this pleasure; because the passages through which the semen passes are narrower, the wetness gushes forth with a more delightful pleasure. And as a result of the sexual itch which arises from this pressure, they are more delighted and liberated. But bonds are more difficult in older men, whose powers are half dead, whose organs and passages are spent, and whose semen is not abundant. Precisely the same thing is found proportionally in the other emotions which have an analogy or contrast or dependence on the passion of love.
